Abstract
Description
- This invention relates to coatings for hard plastics and wood substrates.
- Industrial paints and coatings must satisfy a number of competing requirements. For example, the hardened or cured coating may require a glossy appearance, solvent resistance, or resistance to detergents or other alkaline treatments. Some previously-employed coating systems have become unacceptable for environmental reasons, such as their excessive emissions of solvents now classified as volatile hazardous air pollutants (VHAPs) or volatile organic compounds (VOCs). Coatings applied to plastics may need to be dried or cured in an oven so that the coated parts can be quickly processed and shipped or stored. The dried or cured coating may also require good blocking resistance, especially when freshly-coated parts must be stacked together, or when coated parts must be shipped in conditions (e.g., inside tractor trailers) which may expose the coated parts to elevated temperatures. For some applications such as plastic molding manufacture, coated plastic parts or stock are deliberately bent or otherwise deformed (sometimes with the assistance of heat) in a subsequent manufacturing step. In such instances the coating should remain sufficiently well-adhered to the plastic substrate so that the coating preserves its functional and appearance features after the deformation step.
- Wood-frame windows and other wooden architectural elements that will be exposed to outdoor conditions are often protected by the manufacturer by dipping or otherwise treating the wood with a preservative containing wax, mildewcide and other ingredients. The thus-coated pieces are dried and then topcoated with a clear or sometimes pigmented stain or paint. The wax in the preservative can make it difficult for the topcoat to adhere well to the treated wood substrate.
- From the foregoing, it will be appreciated that what is needed in the art are coating compositions that will adhere well to hard plastics and to wood treated with wax-containing preservatives. Such compositions and methods for their use are disclosed and claimed herein.
- Many of the solvents used in early coating compositions provided improved “bite” that materially aided coating adhesion. Removal or replacement of such solvents with alternative materials may cause the resulting coating to fail customer adhesion requirements. This loss of adhesion may be compensated for to some extent by adding one or more surfactants to the coating composition, but doing so may also unduly reduce the chemical resistance of the thus-modified coating.
- Reichhold Inc. supplies a chlorinated polyolefin-modified acrylic emulsion (now called AROLON™ PW-5000) said to have low VOC levels and excellent adhesion to polypropylene and thermoplastic olefin substrates. The manufacturer recommends inclusion of a coalescing solvent and use of a 30 minute bake cycle at 80° C. (176° F.) in order to obtain good film formation and substrate adhesion. The recommended 80° C. oven temperature can undesirably deform polyvinyl chloride (PVC), a widely-used material for exterior architectural elements. A practical upper oven temperature limit for drying or curing coatings on PVC and many other plastics is about 65° C. (150° F.).
- The present invention provides, in one aspect, a coating composition comprising a mixture of:
-
- a) chlorinated polyolefin-modified acrylic latex emulsion,
- b) polyurethane dispersion,
- c) non-gelling self-crosslinking acrylic emulsion, and
- d) glycol-based solvent,
wherein the composition contains sufficient non-gelling self-crosslinking acrylic emulsion and glycol-based solvent so that a 0.1 mm wet thickness layer of the composition will form a tack-free film when heated at 65° C. for fifteen minutes, and the glycol-based solvent is selected so that the coating composition is shelf stable. The disclosed compositions have particular utility for coating thermally-sensitive plastic substrates (e.g., plastics having low deflection or melting temperatures). The disclosed compositions may also be used on other substrates including higher deflection temperature plastics and wood, especially woods treated with waxy preservatives.
- The invention provides, in another aspect, a coated article comprising a substrate having thereon a hardened continuous coating obtained from a shelf stable mixture of chlorinated polyolefin-modified acrylic latex emulsion, polyurethane dispersion, non-gelling self-crosslinking acrylic emulsion, and glycol-based solvent.
- The invention provides, in yet another aspect, a method for coating plastic or wooden substrates, which method comprises:
-
- a) applying to the substrate a layer of a shelf stable coating composition comprising a mixture of chlorinated polyolefin-modified acrylic latex emulsion, polyurethane dispersion, non-gelling self-crosslinking acrylic emulsion, and glycol-based solvent, and
- b) drying the composition to form a hardened continuous film.
- The disclosed compositions may be packaged in single pack configurations that may be dispensed and applied without requiring the addition of other ingredients, and which may be stored in such packages for a commercially desirable times (e.g., for three months or longer). The disclosed articles and methods provide a hardened polymeric film which may have one or more desirable features including adhesion to the underlying substrate, blocking resistance or chemical resistance.
-
FIG. 1 is a schematic cross-sectional view of a coated article of the invention. - Like reference symbols in the various figures of the drawing indicate like elements. The elements in the drawing are not to scale.
- The recitation of a numerical range using endpoints includes all numbers subsumed within that range (e.g., 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, etc.).
- The terms “a,” “an,” “the,” “at least one,” and “one or more” are used interchangeably. Thus, for example, a coating composition that contains “an” additive means that the coating composition includes “one or more” additives.
- The phrase “low VOC” when used with respect to a liquid coating composition means that the coating composition contains less than about 10 wt. % volatile organic compounds, more preferably less than about 7% volatile organic compounds, and most preferably less than about 4% volatile organic compounds based upon the total liquid coating composition weight.
- The terms “preferred” and “preferably” refer to embodiments of the invention that may afford certain benefits, under certain circumstances. However, other embodiments may also be preferred, under the same or other circumstances. Furthermore, the recitation of one or more preferred embodiments does not imply that other embodiments are not useful, and is not intended to exclude other embodiments from the scope of the invention.
- The phrase “non-gelling” when used with respect to a self-crosslinking acrylic emulsion refers to an acrylic emulsion which, taken alone or together with crosslinkers present in the disclosed coating composition, does not gel when stored for at least three months in a sealed container at room temperature.
- The phrase “shelf stable” when used with respect to a coating composition means that after storing the coating composition for at least three months in a sealed container at room temperature, the efflux time observed using an S90 ZAHN™ Signature Series Dip Viscosity Cup (from Paul N. Gardner Co.) is not more than twice the efflux time observed when the composition was prepared.
- The phrase “topcoat” refers to a coating composition which when dried or otherwise hardened provides a decorative or protective outermost finish layer on a coated substrate. By way of further explanation, such topcoats may be applied in one or more layers and may be applied to bare or primer-coated substrates. The phrase “primer” refers to a coating composition that is applied in one or more layers to a bare substrate and which if left uncoated without a topcoat would not be capable of withstanding extended outdoor exposure (e.g., exposure equivalent to one year of vertical south-facing Florida sunlight) without visually objectionable deterioration.
- Referring to
FIG. 1 , a coatedarticle 10 of the invention is shown in schematic cross-sectional view.Article 10 includes acoating 14 made from the disclosed compositionadjacent substrate 16.Coating 14 may be applied tosubstrate 16 in one or more layers which may be the same as or different from one another. Coating 14 desirably is both decorative and weather-resistant, and may be applied toarticle 10 at the location wheresubstrate 16 is manufactured, at an intermediate location, or at a location wherearticle 10 will be eventually be used (e.g., aftersubstrate 16 has been attached to a building or other surface). Persons having ordinary skill in the art will appreciate thatsubstrate 16 may have a variety of shapes, sizes and end uses. - A variety of chlorinated polyolefin-modified acrylic latex emulsions may be used in the disclosed coating compositions. Chlorinated polyolefin-modified acrylic latex emulsions normally contain at least particles of modified acrylic polymer, water and one or more surfactants, and may contain additional ingredients that will be familiar to persons having ordinary skill in the art. Representative chlorinated polyolefin-modified acrylic latex emulsions include the above-mentioned AROLON™ PW-5000 emulsion, HARDLEN™ EY-4052, HARDLEN EY-4036 and HARDLEN EY-4071 from Toyo Kasei Kogyo Co. Ltd., the chlorinated polyolefin-modified acrylic latex emulsions described in U.S. Pat. No. 6,277,912 B1, and mixtures thereof. Sufficient chlorinated polyolefin-modified acrylic latex emulsion should be used so that an experimentally significant improvement in adhesion to the desired substrate is observed compared to a composition that does not contain the emulsion. Excessive amounts of the emulsion may cause a reduction in the hardened film quality. Preferably the coating compositions contain about 15 to about 85 wt. % chlorinated polyolefin-modified acrylic latex emulsion, and more preferably about 25 to about 50 wt. %, based on total solids.
- A variety of polyurethane dispersions may be used in the coating compositions. Polyurethane dispersions normally contain at least polyurethane particles and water, and may contain additional ingredients that will be familiar to persons having ordinary skill in the art. The polyurethane dispersion and the coating composition are preferably “NMP-free”, that is, they preferably do not contain N-methyl pyrrolidone in amounts sufficient to require labeling or material safety data sheet listing under applicable regulations. Representative polyurethane dispersions include NMP-containing polyurethane dispersions such as ALBERDINGK™ APU 1012, ALBERDINGK APU 1014, ALBERDINGK APU 1035, ALBERDINGK APU 1060, ALBERDINGK APU 1061, ALBERDINGK APU 1062, ALBERDINGK APU 1068, ALBERDINGK CUR 60, ALBERDINGK CUR 69, ALBERDINGK CUR 99, ALBERDINGK U 325, ALBERDINGK U 3305, ALBERDINGK U 520, ALBERDINGK U 610, ALBERDINGK U 615, ALBERDINGK U 610, ALBERDINGK U 710, ALBERDINGK U 800, ALBERDINGK U 801, ALBERDINGK U 910, ALBERDINGK U 911, ALBERDINGK U 915, ALBERDINGK U 930 and ALBERDINGK U 933 polymer dispersions from Alberdingk Boley, Inc, and NMP-containing polyurethane dispersions such as ALBERDINGK APU 10120 VP, ALBERDINGK APU 10140 VP, ALBERDINGK APU VP, ALBERDINGK APU 10600 VP, ALBERDINGK APU 10610 VP, ALBERDINGK APU 10620 VP, ALBERDINGK CUR 601 VP, ALBERDINGK CUR 991, ALBERDINGK U 3251, ALBERDINGK U 3300 VP, ALBERDINGK U 5200 VP, ALBERDINGK U 6100 VP, ALBERDINGK U 6150 VP, ALBERDINGK U 8001 VP, ALBERDINGK U 9150 VP, ALBERDINGK U 9152, ALBERDINGK U 9160 VP, ALBERDINGK U 9152, ALBERDINGK U 9160 VP and ALBERDINGK U 9800 VP polymer dispersions from Alberdingk Boley, Inc. and POSEIDON™ AB-30F, POSEIDON AB-72F and POSEIDON AB-90F from Quaker Color. Mixtures of polyurethane dispersions may be employed. The polyurethane dispersion may help plasticize the chlorinated polyolefin-modified acrylic latex emulsion, and thus it may be desirable to use increased amounts of the polyurethane dispersion when increased amounts of chlorinated polyolefin-modified acrylic latex emulsion are employed. Preferably the coating compositions contain about 5 to about 50 wt. % polyurethane dispersion, and more preferably about 10 to about 20 wt. %, based on total solids.
- A variety of non-gelling self-crosslinking acrylic emulsions may be used in the disclosed coating compositions. The self-crosslinking acrylic emulsion normally contains at least particles of acrylic polymer, water, and one or more emulsifiers. The self-crosslinking acrylic emulsion is different from the above-mentioned chlorinated polyolefin-modified acrylic latex emulsion. The self-crosslinking acrylic emulsion normally contains a suitable crosslinker such as diacetone acrylamide, a carbodiimide, an aziridine or other material capable of converting a 0.1 mm wet thickness film of the acrylic emulsion and crosslinker to a tack-free state when subjected to moderate heating, e.g., at 65° C. for fifteen minutes. A non-gelling self-crosslinking acrylic emulsion may also be provided by employing an acrylic emulsion that is not self-crosslinking but to which is added a suitable crosslinker, in the form of a separate ingredient in the disclosed coating compositions or as a crosslinker present in one of the other disclosed components. A crosslinker may also be added (as a separate ingredient or as a crosslinker present in one of the other disclosed components) to augment a crosslinker already present in a non-gelling self-crosslinking acrylic emulsion. The amounts and types of such crosslinker(s) are such that when in admixture with the acrylic emulsion, the admixture will be non-gelling for at least three months and a 0.1 mm thick wet film of the admixture subjected to moderate heating will form a tack-free film. The admixture preferably will be non gelling for at least six months, and preferably will fat al a tack-free film when heated at 65° C. for fifteen minutes. The self-crosslinking acrylic emulsion may contain additional ingredients that will be familiar to persons having ordinary skill in the art. Representative self-crosslinkable acrylic emulsions include ALBERDINGK AC 2514, ALBERDINGK AC 25142, ALBERDINGK AC 2518, ALBERDINGK AC 2523, ALBERDINGK AC 2524, ALBERDINGK AC 2537, ALBERDINGK AC 25381, ALBERDINGK AC 2544, ALBERDINGK AC 2546, ALBERDINGK MAC 24, and ALBERDINGK MAC 34 polymer dispersions from Alberdingk Boley, Inc.; EPS 2538 and EPS 2725 acrylic emulsions from EPS Corp.; RHOPLEX™ 3131-LO, RHOPLEX E-693, RHOPLEX E-940, RHOPT E-1011, RHOPLEX E-2780, RHOPT HG-95P, RHOPLEX HG-700, RHOPT FX HG-706, RHOPLEX PR-33, RHOPLEX TR-934HS, RHOPLEX TR-3349 and RHOPLEX™ VSR-1050 acrylic emulsions from Rohm and Haas Co.; RHOSHIELD™ 636 and RHOSHIELD 3188 polymer dispersions from Rohm and Haas Co.; JONCRYL™ 1972, JONCRYL 1980, JONCRYL 1982, JONCRYL 1984 and JONCRYL 8383 acrylic emulsions from BASF Corp.; NEOCRYL™ A-1127, NEOCRYL A-6115, NEOCRYL XK-12, NEOCRYL XK-90, NEOCRYL XK-98 and NEOCRYL XK-220 acrylic latex polymers from DSM NeoResins, Inc., and mixtures thereof. Preferably the coating compositions contain about 10 to about 80 wt. % self-crosslinkable acrylic emulsion, and more preferably about 30 to about 65 wt. %, based on total solids.
- A variety of glycol solvents may be used in the coating compositions. The glycol solvent helps reduce viscosity and may aid wetting or film coalescence. Representative glycol solvents include ethylene glycol, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol monobutyl ether, ethylene glycol-2-ethylhexyl ether, propylene glycol, propylene glycol methyl ether, propylene glycol ethyl ether, propylene glycol monobutyl ether, propylene glycol-2-ethylhexyl ether, diethylene glycol, diethylene glycol methyl ether, diethylene glycol ethyl ether, diethylene glycol monobutyl ether, diethylene glycol-2-ethylhexyl ether, dipropylene glycol, dipropylene glycol methyl ether, dipropylene glycol ethyl ether, dipropylene glycol monobutyl ether, dipropylene glycol-2-ethylhexyl ether, and mixtures thereof. Hydrophilic glycol solvents (e.g., propylene glycol methyl ether or dipropylene glycol monomethyl ether) are preferred. Mixtures (e.g., mixtures of dipropylene glycol monomethyl ether and ethylene glycol monobutyl ether) may provide better wetting on some substrates than will be obtained when only a single glycol solvent is employed, and may help discourage changes in coating composition viscosity during storage. For example, coating compositions containing only ethylene glycol butyl ether may exhibit an unacceptably high viscosity increase in the span of a few days or weeks, whereas replacing part of the ethylene glycol butyl ether with another glycol solvent such as dipropylene glycol monomethyl ether may greatly reduce the extent to which viscosity increases occur. Selection of such mixtures may be made empirically, preferably using a clear coating composition prepared without pigments since such clear coating compositions appear to be more susceptible than pigmented coating compositions to viscosity increases when stored. Preferably the coating compositions contain about 25 to about 80 wt. % glycol solvent(s), and more preferably about 30 to about 65 wt. %, based on total solids.
- The coating compositions normally will contain water, as a component of the starting materials or as an added ingredient. Preferably the coating composition contains sufficient water so that about 20 to about 80 wt. % solids and more preferably about 35 to about 55 wt. % solids are present when the composition is applied to a substrate.
- The coating compositions may contain additional reactive or nonreactive monomers, oligomers or polymers, crosslinkers, catalysts or initiators. For example, the addition of a low viscosity reactive epoxide diluent (e.g., HELOXY™ Modifier 48 from Resolution Performance Products added at approximately the same solids weight as the chlorinated polyolefin-modified acrylic latex solids) and an optional catalyst (e.g., adipic dihydrazide from Kowa American Corp. added at approximately 0.3% based on the total composition solids) may provide an improvement in alcohol or methyl ethyl ketone double rub resistance.
- The coating compositions may contain a variety of other adjuvants that will be familiar to persons having ordinary skill in the art. Representative adjuvants are described in Koleske et al., Paint and Coatings Industry, April, 2003, pages 12-86, and may include surfactants (e.g., in addition to those which may be present in the acrylic emulsion starting materials), pigments, colorants, dyes, dispersants, defoamers, thickeners (e.g., hydrophobic ethoxylated urethane resin (HEUR) thickeners, and hydrophobically-modified, alkali-soluble or alkali-swellable emulsion (HASE) thickeners), heat stabilizers, leveling agents, coalescents (e.g., in addition to the glycol ethers), biocides, mildewcides, anti-cratering agents, curing indicators, plasticizers, fillers, sedimentation inhibitors, waxes, ultraviolet light absorbers, optical brighteners, and the like. The use of a filler such as talc and a wax such as an oxidized polyethylene wax homopolymer may help improve mar resistance. The types and amounts of these and other adjuvants typically will be empirically selected for use with the particular application and curing equipment at a given manufacturing site. The types and amounts of the glycol solvent(s) and other ingredients in the coating composition desirably are selected so that the coating composition is shelf stable for at least three months, at least four months, at least five months or at least six months when stored in single pack form in a sealed container at room temperature.
- For some applications it will be desirable to combine the above-described polyurethane dispersion, self-crosslinking acrylic emulsion and glycol solvent (viz., to exclude the chlorinated polyolefin-modified acrylic latex emulsion) and use the resulting mixture as a primer over which may be applied a topcoat of the disclosed coating composition containing the chlorinated polyolefin-modified acrylic latex emulsion. Preferably such a primer contains about 5 to about 50 wt. % and more preferably about 10 to about 20 wt. % polyurethane dispersion based on total solids; about 10 to about 80 wt. % and more preferably about 30 to about 65 wt. % self-crosslinkable acrylic emulsion based on total solids; about 10 to about 50 wt. % and more preferably about 15 to about 30 wt. % glycol solvent based on total resin solids; and sufficient water so that about 20 to about 80 wt. % solids and more preferably about 35 to about 55 wt. % solids are present when the primer is applied to a substrate.
- The disclosed coating compositions may be applied to a variety of substrates. Representative plastic substrates include PVC, polystyrene (PS), thermoplastic polyolefins (TPOs) including polyethylene (PE) and polypropylene (PP), acrylonitrile-butadiene-styrene (ABS), polycarbonate (PC), nylon, polyethylene terephthalate (PET) and other polyesters including filled polyesters such as fiberglass. The plastic substrate may have a bare (viz., unprimed) or previously-coated (e.g., primed or topcoated) surface. Representative wood substrates include hardwood species such as ash, birch, cherry, mahogany, maple, oak, poplar, teak, hickory and walnut, and softwood species such as cedar, fir, pine and redwood. The wood substrate may be solid or veneered, and may have a raw (viz., not primed or treated) surface or a surface that has been treated or coated with a variety of compositions including the above-mentioned waxy preservative treatments. The disclosed compositions may be applied using a variety of methods that will be familiar to those skilled in the art, including spraying, brushing, roller coating, flood coating and dipping. The compositions may be applied at a variety of wet film thicknesses. Preferably the wet film thickness is such as to provide a dry film thickness of about 13 to about 130 μm (about 0.5 to about 5 mil) and more preferably about 25 to about 75 μm (about 1 to about 3 mil) for the hardened coating. The applied coating may be hardened using a variety of drying devices that will be familiar to persons having ordinary skill in the art. Preferred heating temperatures for hardening the coating compositions are about 50° to about 65° C., and more preferably about 60° to about 65° C., and preferred heating times are less than 15 minutes, less than 10 minutes, less than six minutes or less than five minutes.
- The disclosed coated articles may be used for a variety or purposes. Representative end-use applications include architectural elements such as windows, doors, moldings and jambs and other elements used on or around openings; furniture; kitchen cabinetry; engineered flooring; and marine trim or components.
- The cured coating compositions may be evaluated using a variety of tests including those described below:
- Immediately after removing a coated substrate from the curing oven, a fingernail is used to make or attempt to make a 5 cm long scratch in the coating. The coated panels are rated as follows:
-
- 1—No film (coating completely removed).
- 2—Coating is easily removed but leaves a film.
- 3—Coating is removed over more than 1 mm but less than one half the distance scratched.
- 4—Coating is removed over less than 1 mm.
- 5—No delamination of paint (no coating removed).
- An X-ACTO™ knife (from Elmer's Products, Inc) was used to make an x-scribe pattern on the cured coating composition. 3M™ No. 250 Tape (from 3M Company) was applied over the scribe pattern, pressed to remove bubbles and stripped away. A visual evaluation was used to determine if coating delamination occurred. The coated panels were rated according to the same 1 to 5 scale used for Hot Adhesion testing.
- The manner in which the paint atomized and leveled during spraying is subjectively evaluated. The coated panels are ranked relative to one another on a 1 to 5 scale, with a 1 rating representing poor breakup and an undulated film, and a 5 rating representing good atomization and a smooth film.
- Cured coating gloss is measured using a 60° gloss meter and the procedures of ASTM D 523.
- Using C clamps, 10 cm×10 cm coated substrates are clamped face to face by closing the clamps one complete turn beyond the point of initial substrate contact. The clamped coated panels are placed in a 52° C. oven for 24 hours, then removed and rated on a 1 to 10 scale as follows:
-
- 1—Panels can not be pried apart.
- 2—Panels require a tool to be pried apart.
- 3—Panels stuck with a glossy pressure spot and paint transfer.
- 4—Panels stuck with a glossy pressure spot and no paint transfer.
- 5—Panels stuck, but can be pried apart by hand with no glossy pressure spot and no paint transfer.
- 6—Panels exhibit slight cohesion with a glossy pressure spot and paint transfer.
- 7—Panels exhibit slight cohesion with a glossy pressure spot and no paint transfer.
- 8—Panels exhibit slight cohesion with no glossy pressure spot or paint transfer.
- 9—Panels fall apart when opened and have a glossy pressure spot.
- 10—Panels fall apart when opened without a glossy pressure spot, paint transfer or other noticeable defect.
- Using (except as shown below) the Detergent Resistance procedure described in American Architectural Manufacturers Association (AAMA) Voluntary Specification 613, coated substrate panels are soaked for 72 hours at 38° C. in a 3% detergent solution, removed from the detergent, rinsed with water, wiped dry and allowed to recover at room temperature for 15 minutes. Once dry, the entire coated portion of the soaked panel is scribed with an X, taped with PERMACEL™ 99 polyester/fiber packaging tape (from Permacel), and evaluated to make sure that all entrapped air bubbles have been removed. The tape is sharply pulled off at a right angle to the coated substrate, and the coated panels are rated on a 0 to 5 scale as follows:
-
- 0—Coating removed from panel
- 1—Coating remains on panel but in a wet, gummy state.
- 2—Some coating removed from panel and some white residue on tape.
- 3—Coating not removed from panel, lots of white residue on tape.
- 4—Coating not removed from panel, some white residue on tape.
- 5—Coating not removed from panel and nothing showing on the tape.
- An S90 ZAHN Signature Series Dip Viscosity Cup is held by its bail and immersed into a sample of the coating composition at 25° C. The cup is held vertically by inserting an index finger into the bail, and the cup is lifted from the coating composition using a quick, steady motion. A timer is started when top edge of the cup breaks the surface. The cup is held no more than 150 mm above the sample and the 25 mm long portion of the stream immediately beneath the cup outlet is examined. The timer is stopped when the first definite break is observed in that 25 mm stream portion.
